The Straw Top and Infuser turns your Ceres Chill outer chamber into a fruit-infusing water bottle. Here's how it compares to the original lid and when it's worth adding.
Quick Answer
The Straw Top and Infuser is a stainless fine-mesh lid that replaces your chiller's original cap so the outer chamber becomes a straw-ready drink bottle for ice water, cold-brewed tea, or fruit-infused drinks. If you already carry your Ceres Chill daily and want one vessel for hydration and milk storage, it's a cheap, useful add-on. If you only use the chiller for milk and never sip from the outer chamber, your original lid already does that job.
What the Straw Top Actually Changes
Your chiller's outer chamber is the part that holds ice and water around the inner milk chamber. The Straw Top and Infuser screws on in place of the standard lid and adds two things: a straw opening and a stainless fine-mesh infuser basket. That means the same chamber that keeps milk cold can also hold cucumber water, mint and lemon, or loose-leaf tea while you're out.
This is a lid swap, not a new bottle. You keep the chiller body you already own, and the conversion only affects the outer chamber. The inner chamber and its milk-storage function are untouched, so you can still store milk on the same outing.
Straw Top vs. the Original Lid: The Real Trade-Offs
The original lid is built for sealing and carrying. It's the lid you want when the chiller's main job is protecting milk through a commute, a flight, or a full day out. It doesn't offer a straw or an infuser, but it also doesn't ask you to think about whether the straw opening is closed before you toss the chiller in a bag.
The Straw Top trades that single-purpose simplicity for versatility. You gain sipping and infusing, and you take on a little more attention: check that the straw opening is seated, and empty the infuser basket before it sits too long. If you're the kind of person who already carries a separate water bottle, this lid lets you leave that bottle at home — which is the whole point of a drink bottle conversion.
How to Use It as a Fruit Infuser
Fill the outer chamber with water and ice, add fruit, herbs, or tea leaves to the fine-mesh basket, and screw the lid on. The mesh keeps solids out of your straw, so you get flavor without seeds or leaves clogging the opening. Soft fruit like berries and citrus slices release flavor quickly; firmer items like cucumber and ginger need a little more time.
Because the outer chamber is also your cooling chamber, this works best on days when you're drinking the water rather than storing milk for hours. If you need maximum chill time for milk, use the outer chamber for ice and water only and skip the infuser until you're ready to drink.
- Add fruit or tea to the basket, not directly to the chamber, so the straw stays clear.
- Rinse the mesh basket soon after use — dried fruit pulp is harder to clear.
- Pair it with the Day-Tripper bundle if you want the chiller and a pump bag in one purchase.
Straw Top Trade-Offs at a Glance
- Versatility vs. simplicity: The Straw Top adds sipping and infusing to the outer chamber, but the original lid is a simpler seal-and-go option with nothing extra to check. Choose the Straw Top if you'll actually drink from the chiller; keep the original lid for milk-only days.
- Hydration vs. maximum chill: Using the outer chamber for infused water means you're drinking the ice water that would otherwise extend cooling time for stored milk. Don't infuse on days when you need the chiller's full cooling window for milk.
- Cost vs. carrying less: At USD 11.55 (catalog comparison price USD 16.50), the Straw Top costs less than a separate insulated water bottle and lets you leave one bottle at home. It pays off fastest for daily commuters and anyone already carrying a chiller plus a water bottle.
Product Facts
- Straw Top and Infuser: Stainless fine-mesh Straw Top and Tea Infuser lid that transforms the outer chamber into a tool for ice-cold water, steeped tea, and hot or cold flavor-infused beverages. This is the accessory that makes the drink bottle conversion possible, and the mesh is what keeps fruit and tea leaves out of your straw.
- The Day-Tripper - citymouse x Ceres Chill: The Day-Tripper bundle pairs the OG+ Chiller, which the catalog describes as bringing cooling power for 24 hours, with the citymouse Park Bag for pump parts, snacks, and pump wipes. If you're building a full day-out setup, this bundle covers storage and organization together, so the Straw Top becomes an add-on rather than a standalone purchase.
- Personalized Bottle Warming Gift Bundle: The Personalized Bottle Warming Gift Bundle pairs the OG+ Chiller with a Bloom Bottle and warms milk by adding hot water to the chiller and waiting 7-10 minutes; it is final sale and comes with a slow flow nipple. This is the bundle to choose if warming milk matters more to you than sipping from the outer chamber, since the Straw Top does not warm anything.
